Residents of a rural Pennsylvania county who live near natural gas wells reported more health problems than their neighbors who live farther away. That and other findings by a University of Washington researcher raise questions about the health effects of the practice known as fracking.
Researchers went door to door in tiny Washington County, in southwestern Pennsylvania, where gas is extracted by underground hydraulic fracturing. They didn’t tell residents they were there investigating fracking, calling it simply a general environmental health survey. They asked randomly selected households representing almost 500 people about a number of different of symptoms.
